Advice from VeteranLoL-GAF:
As Cait I often win my lane, whether it's top, mid, or bot. I am usually the first to get a tower on either team, or I'm close to it. By the time I get tower, I have Greaves, BF, and Zeal. I join other lanes, and take their towers.
So now their 3 Outer towers are gone.
I often find myself, and the team, lost. We've gained a massive gold/xp advantage and I have no idea how to make use of it. Ball up and push?
Also, it's really disheartening to repeatedly take lanes and win them, only to end up losing.
